Relative dating (steno's laws): long before geologists tried to quantify the age of the earth they developed techniques to determine which geologic events preceded another, what are termed relative age” relationships. Geologic time scale: precambrian period relative dating puts the events in sequential order (or for any of the geologic history of earth. Essentially, relative dating is the determination of the order in which a sequence of geologic events occurred understanding the relative time of these events helps geologists to interpret geologic history the ability to interpret geologic history has enabled geologists to develop a more precise geologic time scale. Activity 7: relative dating the geologic time scale was initially developed by determining the relative ages of rock units, first in europe, and then in other parts of the world most of this work was done in the 1700s and 1800s.
